Enhance query performance analysis and dashboard styles

[ric-v]

This pull request marks the v1.0.0 production-stable release of PgStudio, introducing major improvements in stability, security, documentation, and test coverage. It addresses all critical TypeScript compilation errors, completes a comprehensive security audit, expands user and developer documentation, and updates test and coverage tooling for production readiness. The release also documents known limitations and establishes API stability guarantees for the 1.x series.

Release and Documentation Updates:

• Added v1.0.0 release notes, migration guide, security audit, security review, and API stability contract documentation. Updated README.md and MARKETPLACE.md with a feature matrix, known limitations, and new links to release materials. [1] [2] [3] [4] [5]

Security and Stability Improvements:

• Fixed three critical TypeScript errors blocking compilation and CI: regex escaping in ServerLogPanel.ts, disposal state tracking in ActivityMonitorPanel.ts, and type safety for data generation strategies in MockDataPanel.ts. Details and verification are documented in FIXES_APPLIED.md.

Test Coverage and Quality Gates:

• Added and expanded unit tests for SQL formatting and dashboard components, improved test assertions for query analysis and performance tracking, and updated coverage thresholds and ignore/include patterns for phased coverage (.nycrc, .c8rc.phase-handlers.json, .c8rc.phase-utils.json). [1] [2] [3]

CI/CD and Workflow Updates:

• Changed all GitHub Actions workflows to be triggered only via workflow_dispatch (manual), removing automatic triggers on push, PR, and schedule for codeql.yml, fortify.yml, publish-nightly.yml, and test.yml. [1] [2] [3] [4]

Tooling and Formatting:

• Added .prettierignore and .prettierrc.json for consistent code formatting and to ignore build artifacts and coverage outputs. [1] [2]
